Px4-autopilot: python import error: ImportError('No module named toml',)

[zouboan]

I'm using Ubuntu 14.04LTS

I tried to compile v1.8.0:
sudo make px4fmu-v3_default
Got the error:

('python import error: ', ImportError('No module named toml',))

Required python packages not installed.

On a GNU/Linux or MacOS system please run:
sudo pip install numpy toml

On Windows please run:
easy_install numpy toml

I tried installing with both pip and with apt-get and it installed properly. But, whenever I run the make of PX4 I get the same error.

16.04 LTS is the version of Ubuntu all our testing is done on. 14.04 might work, but it isn't "supported".

I would try installation using our convenience scripts: http://dev.px4.io/en/setup/dev_env_linux.html

They install toml as part of this:

sudo apt-get install python-argparse python-empy python-toml python-numpy python-dev python-pip -y

[MaEtUgR]

@zouboan I'm not sure if that is related to your problem but when I was working on the Cygwin Toolchain to support PX4 development under Windows I had the exact same error happening when building. I followed down where this comes from: https://github.com/PX4/Firmware/blob/b7d7d1209b331a571b205d5a0006e543c1891357/src/lib/mixer/geometries/tools/px_generate_mixers.py#L41-L53 and tried to manually import toml and numpy by manually executing the following commands on the bash shell:

import toml
import numpy
exit()

I found out that both packages were in fact installed but numpy failed to import whenever I ran the cygwin bash shell without the --login parameter (remember I'm on Windows). I honestly have no clue why this plays a role or if any of that translates to Ubuntu but you may try to look into the "non-login shell fails to import numpy" direction as well.

This issue has been automatically marked as stale because it has not had recent activity. It will be closed if no further activity occurs. Thank you for your contributions.

[MaEtUgR]

I'm assuming this was solved. I could try the latest toolchain setup convenience scripts in a 14.04 VM but if there's no demand I won't go through that effort.

[machenxiang]

I have a new way to solve the problem.
First, git clone https://github.com/uiri/toml.git
Second, cd toml
Third, python setup.py install

[jlm345]

I have got the same error when
make posix_sitl_default gazebo
I solved it by modifying the PYTHONPATH and solve it:
export PYTHONPATH=/usr/bin/python
Hope it helps!

[MaEtUgR]

I honestly have no clue why this plays a role or if any of that translates to Ubuntu but you may try to look into the "non-login shell fails to import numpy" direction as well.

Update: By now I learned that it's not good to install python packages by running pip as root from https://dev.to/elabftw/stop-using-sudo-pip-install-52mn For a lot of packages it will result in a library installation that is tied to the root account and you can't import them using a different user.
So I think the solution is to run pip install --user toml and afterwards check again if you can import it as your user and it should work just fine.

I have same troubles. My system is : ubuntu 16.04 + kinetic + gazebo 9
when I open a shell:

python
import toml

and it works.
but i use :
make px4_sitl_default gazebo
it errors:

I think the means is told me : empy isn't installed.

same errors still exist.
who can tell me how to solve it ?
thank you

I have got the same error when
make posix_sitl_default gazebo
I solved it by modifying the PYTHONPATH and solve it:
export PYTHONPATH=/usr/bin/python
Hope it helps!

hi, I env found : PYTHONPATH is : PYTHONPATH=/opt/ros/kinetic/lib/python2.7/dist-packages

maybe

if you want to keep the ROS path,you can try this one:
export PYTHONPATH=/usr/bin/python:/opt/ros/kinetic/lib/python2.7/dist-packages

You may try this.
Inquire the pythonPath Result, and set PYTHONPATH accurately.
pip3 --version
My Result:
pip 19.3.1 from /usr/local/lib/python3.5/dist-packages/pip (python 3.5)
Then set PYTHONPATH as this
export PYTHONPATH=/usr/local/lib/python3.5/dist-packages:${PYTHONPATH}
Then pip install packages for "No module named" should work!

You are using pip version 8.1.1, however version 20.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

and i found, my system have installed python3 and python2. i open shell, use :

python
import toml

it right

but when i try:

python3
import toml

it errors:No module named 'toml'

i think this errors results in px4's errors.
but i can't know how to solve.

[julianoes]

Ok, and you have done?

pip3 install --user toml

If not, please paste the output of:

which python
